technology that uses electrical impulses to stimulate the nerves in the

end of your finger. The technology works using an extra layer applied to

the whole surface of the screen rather than just a few buzzing spots. The result is that it can recreate the sensation of different surfaces that correspond to what’s onscreen. Silk, sandpaper, a ball, rippling corrugated iron, all these can be emulated by this clever tech.

When we tried the technology last year we had mixed results with yours truly struggling to sense the electric pulses through the tough manly skin of my fingers, but ex-news editor Gordon Kelly could quite distinctly feel the changing surfaces and patterns.

An exciting new development for touch technology or a bit of a gimmick? Let us know your thoughts in the comments.
